DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENTS

Before explaining the present invention in detail, it is to be understood that the invention is not limited to the particular embodiments and that it can be practiced or carried out in various ways.

With reference to the Figures, FIG. 1, FIG. 2, FIG. 3, and FIG. 4 are representations of a choke and method for treating a flow stream from a well having large diameter particulate matter.

One of the benefits of this invention is that it can remove damaging solids from an oil well or natural gas stream so as not to damage down stream equipment, such as separators, pipe line and refining equipment, by inserting an integral solids receptacle into the chamber, the solids are easily and efficiently removed from the flow stream. In this design, the flow stream inlet is in one embodiment below the flow stream outlet from the choke, which makes it very difficult for heavier particles to rise up to the flow stream outlet, so using gravity and the natural circulation of the flow stream in the chamber, the large diameter heavier particulate matter is more easily trapped in the integral solids receptacle in the chamber.

Another benefit of the invention, is that the invention can reduce the velocity of the flow stream between 3 and 5 times the initial intake velocity into the housing of a choke. The benefit of the reduction of the velocity of the flow stream is again to restrict the ability of the large diameter particulate to reach the flow stream outlet, and drop out of the flow stream into the solids receptacle in the chamber of the housing of the choke.

Environmentally, the removal of large diameter particulate matter at this stream stops damage to equipment which can cause leakage into the environment, or explosions which can harm people down stream. Pollution from leakage caused by large particles jamming up pipelines is a serious problem, and the toxic clean up can be expensive and harmful to wildlife. The invention is designed to reduce these hazards and help solve these problems.

FIG. 1 depicts the side view of a choke (10) for a flow stream (50) from a well such as an oil or natural gas well having large diameter particulate matter (42).

The flow stream is from a production well, drilling well or combinations thereof. The velocity of the flow stream is reduced significant significantly as it moves from the flow stream inlet (24) to the flow stream outlet (51), and is reduced between about 3 and 5 times from the flow velocity at the flow stream inlet (24) to the flow velocity at the flow stream outlet (51).

The chamber (15) is in communication with a flow stream outlet (51) and the flow stream inlet (24) is located on a plane below the flow stream outlet (51). The method also permits large diameter particulate matter (42) to fall from the flow stream inlet (24) into the integral solids receptacle (30). A stream is formed without large diameter particulate matter (42). This stream is then flowed flows to the flow stream outlet. A needle (20) and choke face (26) are used to control the flow velocity of the flow stream, which is a hydrocarbon stream without large diameter particulate solids out of the chamber (15) to the flow stream outlet.

The method allows, periodically, interrupting the flow stream by engaging the needle (20) with the choke face (26) to remove additional large diameter particulate matter (42) which are still circulating from in the chamber (15). On necessity, the method allows removing the large diameter particulate matter (42) from the integral solids receptacle (30) in the chamber (15) through the solids removal outlet (39). Additionally, the method allows for a step of forming a sealing engagement between the choke face (26) and the needle (20) using a seat (22).

In an alternative embodiment, the method allows for the chamber to be in communication with a flow stream outlet (51), and the flow stream inlet (24) is located on a same plane or is identical to the flow stream outlet (51).

While this invention has been described with emphasis on the preferred embodiments, it should be understood that within the scope of the appended claims, the invention might be practiced other than as specifically described herein.
